Orbis - The Stanford Geospatial Network Model of the Roman World - reconstructs the time cost and financial expense associated with a wide range of different types of travel in antiquity. The model is based on a simplified version of the giant network of cities, roads, rivers and sea lanes that framed movement across the Roman Empire. It broadly reflects conditions around 200 CE but also covers a few sites and roads created in late antiquity. It includes an interactive route map, by which you can discover the fastest, cheapest or shortest connection between two locations of your choice, selecting the modes and means (here called options) of transport, and the month of the year.
